Hi,
I've got a problem with a parcelable ArrayList.
I made a custom Button called MyButton and the ArrayList is a generic
one. So it only takes MyButton objects.
Passing the list from on Activity to another is not the problem. In
the receiving Activity the Log says, it has some elements, but if i
read specific values (like height and text of the button), it always
says null or 0.
public class MyButton extends Button implements Parcelable{
private HashMap<String, String> map;
public static Context context;
public MyButton(Context context){
super(context);
this.context = context;
map = new HashMap<String, String>();
}
public MyButton(Context context, AttributeSet attrs){
super(context, attrs);
}
public MyButton(Parcel in){
super(context);
map = new HashMap<String, String>();
readFromParcel(in);
}
public static final Parcelable.Creator<MyButton> CREATOR = new
Parcelable.Creator<MyButton>() {
public MyButton createFromParcel(Parcel in) {
return new MyButton(in);
}
public MyButton[] newArray(int size) {
return new MyButton[size];
}
};
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(map.size());
for (String s: map.keySet()) {
dest.writeString(s);
dest.writeString(map.get(s));
}
}
public void readFromParcel(Parcel in) {
int count = in.readInt();
for (int i = 0; i < count; i++) {
map.put(in.readString(), in.readString());
}
}
public String get(String key) {
return map.get(key);
}
public void put(String key, String value) {
map.put(key, value);
}
}
If you could have a look at my code and tell me what i made wrong, I
would be very glad.
